Man avoided a fine after blowing the whistle on the cartel and the others had their fines cut by 10% for pleading guilty.

The companies had been accused of colluding to fix prices and avoid the costs of stricter pollution rules around emissions by passing them on to consumers.

Between them, they produce nine out of every 10 medium and heavy trucks sold in Europe.

‘Cosy’

“Instead of colluding on pricing, the truck manufacturers should have been competing against each other – also on environmental improvements,” European Commission competition chief Margrethe Vestager said in a statement.

The Commission added that the plan was formed at a secret meeting between senior managers in a “cosy” Brussels hotel.

It also stressed that the investigation did not reveal any links between the cartel and allegations of carmakers cheating on emissions control testing.

Scania’s fine is the second highest in the case, behind the 1.01bn euro penalty given to Daimler.

The company has denied any wrongdoing and because it did not agree to settle the case with the others, it now has the option of challenging regulators in court.
